Note générale :	In early 1979, a retrieval was made for all phytoplankton data contained in the computerized data file of the U.S. geological survey. The retrieval revealed the analytical resultats at 17,959 sample coolected and processed between october 1973 and october 1978. Of the approximately soo genera of freshwater algae reported in the united states, the US geological survey observed 321 genera in the phytoplankton . Fifty - two genera were considered to be community dominants. This report lists, describes and provides a detailed taxononue key to the identification of 58 genera of algae considerd either commonly occurring or dominant...
